Application August 8, 1945, Serial No. 609,511

2 Claims. (01. 248-146) My invention relates to a supporting stand and more particularly to a stand for supporting that type of wash tubs commonly known as sanitary trays.

Heretofore it was common practice to employ one-half inch standard water pipe in making stands for sanitary trays. In accordance with prior art practice, standard water pipe was cut in pieces to form four vertical legs at the corners, a horizontal runner at each side, and a front runner. Each back leg was secured to an end of a side runner by the use of standard plumbing Us. The other end of each side runner, one end of the horizontal front runner, and one end of a front leg were secured together by a standard plumbing three-way L.

This prior art practice has been uneconomical in that it required considerable amount of pipe cutting and threading and the use of two standard Ls and two three-way Ls.

A further difficulty of the said prior art tray stands lay in the fact that it often required individual fitting during installation to get all four legs to rest evenly on the floor. A further disadvantage of such prior art tray stands was the amount of pipe needed to provide the necessary support. Further, such prior art tray stands did not provide support in some necessary places.

It is an object of my invention to provide a tray supporting stand which may be bent from tubing, as standard water pipe in all respects except the addition of one leg member which is welded at a desired location.

It is a further object of my invention to provide a tray stand formed substantially wholly by bending wherein two front leg members and an interconnected single back leg member are provided. It is a more specific object of my invention to provide such a tray supporting stand having two vertical front legs, two horizontal and angularly disposed side arms, a horizontally disposed back arm, and a vertically disposed rear leg welded to said back arm intermediate thereof.

The above mentioned general objects of my invention, together with others inherent in the same, are attained by the mechanism illustrated in the following drawings, the same being preferred exemplary forms of embodiment of my invention, throughout which drawings like reference numerals indicate like parts:

Figure 1 is a perspective view of a tray stand embodying this invention;

Fig. 2 is a view in side elevation of the tray stand of Fig. 1 with a. sanitary tray disposed thereon;

Fig. 3 is a view in front elevation of the structure shown in Fig. 2;

Fig. 4 is a plan of the structure shown in Fig. 2; and

Fig. 5 is a view similar to Fig. 1 of a modified form of my invention.

Referring to the drawings, my tray stand is provided by bending a piece of standard water pipe to provide vertical front leg 6, horizontal side arm 1, horizontal rear arm 8, another side arm 9, and another vertical front leg in. The rear arm 8 lies in a vertical plane which is parallel to the vertical plane of the front legs 6 and H1. The side arms 1 and 9 each lie in vertical planes which are at an angle of substantially 45 to the vertical plane in which the front legs 6 and I0 lie. Intermediate the length of the rear arm 8 and substantially at the middle thereof is secured a rear leg II and securance is made by welding.

Referring to Fig. 4, a sanitary tray of standard construction is shown. This comprises two tubs or compartments l2 and I 3 which have respectively outlets l4 and I5. These outlets are connected with a common drain (not shown). Also, a common air vent (not shown) is provided for each of the tubs i2 and I3 in the common wall 16 of both tubs. This air vent is disposed in alignment with the outlets l4 and [5. Also, because of the shape of the sanitary trays, the center of mass of the tray and the fluid load therein is substantially forward of the rear wall of the tray and toward th middle of the tray. The center of mass of the tray is substantially in alignment with the weakened portion of the structure caused by the outlets l4 and I5 and the air vent therefor. It is common practice to make sanitary trays from sand, cement, and water, and thus we have a type of material having relatively low tensile strength. Thus it is common for sanitary trays, if they develop cracks, to develop the same generally toward the middle of the sanitary tray and in relatively close proximity to the outlets l4 and I5.

Despite the fact that the trays have cracked the prior art tray stands have not been heretofore modified to better support the trays and minimize the tendency of the trays to crack.

In prior art tray stands when pipe fittings were used, the pipe fittings projected above the surface of the pipe and therefore the bottom of the tray was supported locally at four locations adjacent the corners. Thus the use of pipe fittings, as Us or double Ls, not only entailed considerable expense because of the cost of the fittings and the cost of cutting and threading the and thus substantial contact area and supporting bearing surface is provided. Furthermore in my invention the horizontal rear arm 8 extends across the bottom of the center wall N3 of thetray and is there supported to provide a support bearing against the lower surface which has heretofore been the location of most of the cracks in sanitary tubs.

In Fig. 5 of the drawings I have shown a modified form of my invention and as some parts there of are identical in construction and operation with parts of the structure of the previous figure, they will be given similar numbers. Thus in Fig. 5 I have provided front vertical legs 6 and I0 and rear vertical leg ll. Instead of providing horizontal side arm 1, rear arm 8, and the other side arm9, I have shown an arcuate arm I! which functions similarly to parts it replaces. An advantage of providing side arms I and 9 and rear arm 8 is that the pipe may be bent in standard pipe bending machines while if the member I! is providedgreater uniformity obtains if a die member particularly suited for bending the same is employed.

Whether the tray stand takes either form of my invention, it can be made with considerably less pipe than was necessary in. prior art sanitary tray stands. There is considerably lesslabor involved as it ismerely bending of pipe rather than cutting and threading the same. In addition to the savings afforded because of the use of less pipe, I do not employ any pipe fittings and the cost of the fittin s is a very substantial item. Furthermore, I not only save in materials and labor but I provide a better tray stand in that there is continuous bearing surface between my tray stand and the bottom of the sanitary trays instead of local bearing support at the location'of the pipe fittings. Finally, my tray standsprovide a supporting-member at the location of the area where 4 the sanitary trays have heretofore most often cracked.

Obviously, changes may be made in the forms, dimensions and arrangement of the parts of my invention, without departing from the principle thereof, the above setting forth only preferred forms of embodiment.

I claim:

1. A supporting stand for a sanitary tray of the type providing two compartments, adjacent drain holes, and a common air vent comprising a tubular, bent, and substantially rigid pipe forming two vertically disposed front legs for supporting the front end bottom portions of a sanitary tray,

two side arms for supporting the bottom side portions of a sanitary tray and a rear arm for supporting the bottom rear portion of a sanitary tray,

the top of said legs and the top of all of said arms lying in a common plane to provide a uniform support for a sanitary tray; and a vertically disposed tubular pipe rear leg means welded to the lower surface of the rear arm and disposed to support a sanitarytray in close proximity to the drain and vent openings at the center and rear of a sanitary tray.

2. A supporting stand for a sanitary tray of th type providing two compartments, adjacent drain holes, and a common air vent comprising a tubular, bent, and substantially rigid pipe forming two vertically disposed front legs for supporting the front end bottom portions of asanitary tray, and a horizontal portion interconnecting said leg portions having. its upper surface lying in a common horizonta1 plane for supporting the bottom side portions and the bottom rear portion of a sanitary tray; and a vertically disposed tubular pipe rear leg. means welded to the lower surface of the horizontal portion and disposed to support a sanitary tray in close proximity to the drain and vent openings at the center and rear of a sanitary tray.
